Fenty Beauty by Rihanna | Pro Filt’r Instant Retouch Primer – No-shine Primer Approved?

Hey beauties, since I bought the Fenty beauty's Pro Filt'r Instant Retouch Primer I've been reading mixed opinions about their mattifying power. So I made a little experience : I tried three different foundations and applied the primer in just one side of the face. In the end, is this really a matte primer or not?
